Jessica Ennis-Hill has revealed she is expecting her first child and will miss the 2014 Commonwealth Games in Glasgow.

The 27-year-old heptathlete said the news was "very unexpected" but exciting for her and her husband, Andy Hill, who she married in May.

She said: "My plans for 2014 have been completely turned upside down, but having had a couple of weeks to think about things from a career point of view I am 100% set on returning to full time athletics once our baby is born and go for a second gold medal at the Rio Olympics in 2016 - that challenge really excites me.

"But in the short term I will make our baby a priority and enjoy the whole experience as much as possible.

"I am sorry I won't be in Glasgow for the Commonwealth Games, but know it will be an amazing occasion. I will be at home awaiting the arrival of a little Ennis-Hill."

After winning her gold medal in the London Olympics in 2012, Sheffield-born Ennis-Hill was due to be one of the favourites in Glasgow this year.

She suffered a disappointing 2013 as she struggled to recover from an ankle injury in June.

It forced her to miss the British Championships before returning to Loughborough, where she set a personal best in the javelin.

She featured in the London Anniversary Games but pulled out of the World Championships in Moscow four days later because of continuing problems with her ankle.
